RN1, RN2, RN9, RN10, RN11, and RN12 are 330 ohm resistor networks.
RN3, RN4, RN5, RN6, RN7, and RN8 are 150 ohm resistor networks.
Caution:
When reinstalling resistors, you cannot install a 330
ohm resistor into a 150 ohm socket and vice versa. The ohm
value can be found in the part number printed on the resis-
tor. A 330 ohm resistor will have a 330 or 331 included in the
part number printed on the resistor and a 150 ohm resistor
will have 150 or 151.
Note:
When reinstalling resistors, make sure to maintain
pin-1 orientation as shown below.
